742-AlphaCell:构建模拟细胞动态演化的虚拟世界模型

from 聊聊Sci

AlphaCell 是一款创新的生成式虚拟细胞世界模型,旨在通过模拟复杂的细胞动力学来预测生物体对干扰的反应。该研究针对现有模型在基因表示不全、重建精度低及泛化能力差等方面的瓶颈,提出了潜流形纠偏、生物现实重建和通用状态转移三大核心技术。模型通过对超过两亿个单细胞数据进行大规模预训练,构建了一个高维连续的虚拟细胞空间,并利用混合专家网络(MoE)和最优传输条件流匹配技术,将离散的观测数据转化为连续的物理演化轨迹。实验证明,AlphaCell 在跨细胞类型的干扰预测中表现卓越,能够实现高精度的全基因组水平重建。该框架不仅能够处理已知的细胞与干扰组合,还展现了在完全未见过的生物语境下进行零样本预测的强大潜力。这一突破为药物研发和基础生物学研究提供了一个从描述性基因组学向量化预测仿真的重要计算平台。References: Chuai G, Chen X, Yang X, et al.
